焊接和钎焊
焊接和钎焊过程原理相似，填充材料在一个相对低的温度熔化而这种液体填充剂在毛细作用下进入要被焊接的两部分之间。焊接及铜焊一个主要的好处是连接操作是在较低的温度,所以零件很少受热变形而且几乎不会改变金属微观组成。软焊料是相对较软但是很有延展性的焊料(比如铜)延展范围为400 ~ 500MN /㎡。
软钎焊
柔软的合金焊料有锡合金和铅或锡锑、镉或铋,熔化温度70 ~ 300℃范围。液体焊料必须表面很“湿润“这样才能使焊接高效的。这意味着在焊料和被连接的金属之间的组成部分会产生合金。这种类型的合金的产生可能导致固溶体和金属互化物的产生。用软焊料锡会与铜和铁反应生成金属互化物。液体焊料只会湿润金属表面,而所有的焊接面都要做到干净的无油脂保持绝对清洁。氧化膜薄就会迅速形成一种新的金属表面所以必须要用一种焊剂来溶解这个氧化层。使用的焊剂要么是锌氯溶液要么树脂的类型。最常用的是热源软焊为烙铁和铜电焊头。
硬焊
硬焊,或钎焊是利用铜基合金,融化的温度从620℃到900℃来焊接。再说一遍,材料必须是洁净而且焊接处必须使用熔剂。最常用的熔剂是硼砂。硼砂融化在750℃,对许多金属氧化物是一种优良的溶剂。对钎焊来说使用熔剂比使用碱金属氟化物操作温度温度更低。
作为连接处的软焊料因该准备好拟合在一起。在焊接时熔态钎料通过毛细管作用进入焊接处。最常用的热源钎焊是气焊焊炬。燃气常用丙烷或乙炔。通常来说,火焰要用中等或小火焰,但当铜有轻微的氧化时火焰应该被用来减少氢的可能性脆化作用。

Leo girls
She is a listening to country music's Leo girls
Hate hypocrisy, can guess the hearts
Like going to the library, like pedantic
She would sometimes reading in the classroom
Sometimes she would play in the playground
She will spit on unfair
She will praise justice
As the book write and constellation
She is magnanimous and cheap
Perhaps this is the dual personality
Self-confidence vain narcissistic
This is her
A Leo girls
Remember only walk into this girl's heart. Leo
Is that wearing sneakers
Wearing a T-shirt you boys
He never spoke to, it is silence is not dumb
Taylor Swift books now mark good handsome she would say
She would like the gate. Hamlet play happy
She would like Taylor playing a guitar stand in front of you
She she she that Leo girls
Her dream was to become singer
Her dream was to become President
Her dream was to become agents
A putin that open the aircraft to extinguish the forest fire and singing national leader
She wanted to tell that Capricorn boys
Quick appear in her eyes
Otherwise she will be angry
She wanted to apply for an exchange student
To the United States that country
She would sometimes reading in the classroom
Sometimes she would play in the playground
She will spit on unfair
She will praise justice
This is her, a Leo girls
应该是对的，你看看吧!
请注意：如果我们定购的应该是没有顶部没有黑色活结的刺猬，因为它可能对儿童的危险。
是的，这个Squeaker是在刺猬里面加一个很小的工具来发声。
劳烦你发个包涵发声工具和商标标签的新报价。
附件中的图片是我们现在的刺猬上用的标签。
这个标签不要用套索，要把它放在与后腿齐平的高度，在后退中间，同时也在长绒毛和软毛之间。
注意：如果下单，生产的刺猬不可以在顶部有黑色吊绳，这样可能会对儿童造成危险。
这里面的几个名词，不见得很对，我不是做这行的。这应该是玩具，礼品行业的外贸邮件。希望对你有用。
